To the left started out as a new 130 amp Ford MotorCraft type 3G series large case alternator for a Ford F Series Truck The stator was first upgraded to 250 amps then the Quicktifier 420 with two 210 amp rated remote bridge rectifiers were added for a total load carrying capacity of 630 amps at the bridge rectifier will make this alternator the toughest on the market.. When upgrading the output of an alternator you must always upgrade the durability of the bridge rectifier to have a greater amperage load carrying capacity than the output of the alternator it's self.

By adding either the Quicktifier 210 or Quicktifier 420 you go from having 6 diodes at 120 amps load carrying capacity to 12 or 18 diodes with an overall load carrying capacity of 420 or 630 amps, this will make your upgrade tough as nails! Makes your high amperage alternator hold up to higher demand.

Call us and ask if we have an upgrade for your Ford vehicles alternator.

If you purchase a new alternator and Quicktifier we will attach the wires into the alternator at no extra charge. You only need mount the alternator & Quicktifier box then wire it like we show on the Quicktifier web page.
